Route for 19411.12 via RE ROK JIND KLE KKDE is too good rather than PNP KUN Route.
PNP - KUN Route have too much service for UMB CDG, also Gohana have three services to UMB.
How...
more... ROK PNP KUN Route is more efficient than ROK JIND NRW KKDE Route.
On existing Route (via NRW KLE) there is one LR at KKDE, also on your proposed Route (via PNP KUN), there will be one LR at ROK.
ALSO, ON EXISTING ROUTE, IT IS CONNECTING unconnected, HOWEVER ON PNP KUN ROUTE, IT WILL BE NOT TOO GOOD THAN WHAT IT IS NOW.
Agree with your proposal of LHBfication and speedup at least by 2 hours end to end.
